The Collins still has "tight hole" status... we know about the common formations and zones, but the lower end of the well is still never discussed.
I believe it is misleading to state that nothing was found.
If that were the case, there'd be no reason to still have tight hole status, and there never would have been talk about "something there that even the KGS has never seen before" at the time it was drilled.
IMO, safer to say "we don't know" and leave it an open question until if/when there is any indication either way.
Then again, maybe I've got it all jumbled up. *shrugs*
